MACHINE FOR SPINNING CAR-WHEELS.

SPECIFICATION forming part of Letters Patent No. 581,284, dated April27, 1897.

Application filed September 6, 1895. Serial No. 561,650. (No model.) I

To aZZ whom it may concern:

Be it known that 1, JAMES HENDERSON, a citizen of the United States,residing at the city of Three Rivers, in the county of St. J oseph andState of Michigan, have invented certain new and useful Improvements inMachines for Spinning Car-Vheels, of which the following is aspecification. I

My invention relates to improvements in metal-spinning machines, andmore particularly to a spinning-machine for spinning carwheels of thicksheet metal or plates.

As heretofore constructed machines of this class have been difficult ofadjustment. It has been difficult to control the same to secure thedesired results, and the shaft of the spinning-wheel has been more orless likely to become inclined, which prevents its doing good work.

The objects of my invention, therefore, are, first, to provide a machinewhich is positive and powerful in its action; second, to provide meansof adjusting and carrying the spinning-wheel so that it shall move toexactly the desired position; third, to provide improved means ofcontrolling the movement ofthe spinning-wheel, so that it shall beentirely automatic in its act-ion or can be controlled by the operativeat will; fourth, to provide an improved spinning-machine for spinningcar-wheels of sheet metal where the rims are of irregular form.

Other objects and improvements in the machine will appear clearly in thedetailed description of the same.

I accomplish the objects of my invention by the machine and mechanismshown in the accompanying drawings, in which- Figure 1 is a top planview of a spinningmachine embodying all of the features of my invention.Fig. 2 is a front elevation of the machine shown in Fig. 1 with aportion of its frame broken away and the guide-wheels removed. Fig. 3 isan elevation of the machine taken from the left hard of Figs. 1 and 2,being an end elevation of the machine. Fig. 4 is an enlarged detailsectional view of the hydraulic cylinder and its connections foractuating the spinning-roll, taken on line 2 2 of Fig. 1. Fig. 5isasectional View taken on line 5 5 of Fig. 4, looking down. Fig. Sis

Fig. 7 is an enlargeddetail sectional view on line 7 7 of Fig. 6, looking in the direction ofthe little arrows at the end of the section-line. Fig. 8 is a transversesectional view taken on line 8 8 of Fig. 6, looking down. Fig. 9 is asectional view of the cross-head and its connections to the piston-rodof the hydraulic cylinder, taken on line 9 9 of Fig. 4, looking in thedirection of the little arrows at the ends of the section-line. Fig. 10is an enlarged detail sectional view of the adjustable eccentric 7t,appearing clearly in Figs. 4 and 5. Fig. 11 is a sectional View on line11 11 of Fig. 10, looking in the direction of the little arrows at theends of the section-line. Fig. 12 is a vertical sectional View of one ofthe guidingrollers of the spinning-machine, taken on line 12 12 of Fig.1, looking in the direction of the little arrows at the ends of thesectionline.

Similar letters of reference refer to similar parts throughout theseveral views.

Referring to the leti ered parts of the drawings, A is the base whichsupports the remainingpart-s of my improved machine. B B are side piecesprojecting up therefrom, which support the top or table-like portion 0,which is adapted and formed to answer its peculiar purpose. To the rearof the machine are upwardly-projecting brackets B B, which affordbearings to carry the driving-shafts of the machine. The inner bracket13 is also secured by suitable bolts to the rear end of the tableportion O and serves as a support for that part of the machine. Betweenthe side pieces B is supported a central lower table or plate 0, whichis parallel with the top plate 0.

The counter-shaft M is supported in suitable boxes on the bearings B Bto the rear of the machine and bears the usual tight and loose pulleys hfor operating the machine from suitable belt connections. Extendinglongitudinal of the base and supported in suitable boxes D D therein isthe drivingshaft of the machine D, which bears a large gear-wheel D,which meshes with the pinion M above and serves to actuate the entiremachine. A vertical shaft G extends up through the rear portion of thetables 0 and C and bears a suitable bevel-pinion at the bottom, whichmeshes at that point with a bevel-gear E on the shaft G. This shaft G ispermanently held in position and bears the female spinning-roll L, whichis supported above the top of the table (3. In a suitable housing orframe F is supported a movable vertical shaft II, which bears at itsupper end a male spinningroll II, the housing F being movable back andforth over a space of about three inches in suitable guideways, whichpermits the roll to be moved out and in for the purpose of spinning thecar-wheels between the two rolls L and H.

From the top plate 0 to each side of the spinning-rolls areguiding-rolls '1, which are supported in suitable slots and areadjustable to and from the spinning-rolls to properly guide the rim ofthe car-wheel of any size to the same, so that it shall be spun true bybe ing guided in this way. The guiding-rolls are adjusted close to thespinning-rolls when a small car-wheel is being spun and moved fartheraway when a larger wheel is being spun, the points of contact with thetwo guiderolls and the point of contact between the two spinning-rollsdetermining the circle of the periphery of the wheel.

On the driving-shaft D below is a suitable bevel-gear E, which mesheswith the bevelpinion on the lower end of the shaft H. A bracket from thehousing or frame F extends downwardly and a journatbearing box is formedthereon to hold a suitable sleeve which is integral with thebevel-gearE. The bevelgcar E is movable along the shaft D, along asuitable key 1 which fits into a key-seat in the gear E and its sleeve,which permits of the required motion and holds the gear E in mesh withits follower on the lower end of the shaft II, which appears clearly inFig. at.

Between the plates 0 and O is supported a hydraulic cylinder R bysuitable bracket p tojections therefrom. In the cylinder R is a suitablehydraulic piston It, from which extends a piston-stem R, which isconnected by a suitable cross-head with the housing or frame F by asuitable mechanism for actuating the same. This connection from thecross-head of the piston R to the housing or ported in suitable bearingsin the top plate C above and in suitable bearings on the intermediateplate G below, parallel with each other in substantially the samevertical plane.

Suitable shafts project transx'ersel y with the machine through theupper and lower part of the housing F, and the upper shaft is connectedto the upper shaft 7;; by a suitable toggle-joint U U, and the lowershafts 7a and are similarly connected by a similar joint, the jointsbeing adapted to fold toward each other between the top plate 0 and theintermediate plate 0, the toggle-joints being equal andthe shaft-s j and7.: above and below being the same distance apart and in planes parallelto each other.

On the forward end of the piston-stem R is a suitable cross-head,standing in the vertical position, which is connected by links Q Q tothe central joint of the toggle-joints U U above, and below by pins 11,which are suitably secured to the cross-head.

To the ends of shafts P, which are supported by suitable hangers fromthe top plate 0 and by suitable brackets from the intermediate plate C,are secured levers P, bearing segments of gear which project up from thelever below and down from the lever above and mesh in a line oppositethe outer end of the piston-stem It. The outer ends of the upper loversare connected by suitable links Z to the shaft j, and the cutter ends ofthe lower levers are connected, also, by similar links Z to the lowershaft 7'. The levers P 1 and link Z are exactly s 'nnnetrical to eachother and equal.

By examining Fig. at it will be seen that when the water is admitted tothe hydraulic cylinder B it will carry the piston-head R forward, whichwill. actuate, through the links Q Q, the togglejoints U U U U, whichwill carry forward very powerfully the frame or housing F, which willcarry its spinningroll II forward against the spinning-roll L, thespinning-rolls being actuated from the driving-shaft, as heretoforedescribed. As the joints which actuate this spinning-roll II aretoggle-joints, the force with which the spinning-roll is carried forwardis very great. The connections from the shaft j through the levers I,which mesh with each other, prevent any nnequal motion of the top andbottom of the shaft II and serve to actuate the same in exactly thevertical position after the vertical shaft H has been once adjusted tothat position.

The adjustment of the connection to the housing F for adjusting theshaft is accomplished by a disk 7;, supported on the shafts 7t above andbelow, and by rotating the same it will be noticed that as the bearingsare eccentric the bearings of the rear ends of the links U will becarried backward and forward to any required extent for securing aproper adjustment, and when the set-screw is turned into the aperture 10on the periphery of the disk 75 (see Figs. 10 and 11) the same will beheld very securely and with very little strain at that point, owing tothe fact that the bearing-support is eccentric, and consequently doesnot yield easily to the pressure. A shaft 7t extends through the centralportion of the housing or frame F, and to the outer ends of this shaft71 are secured cables Z, which pass ICO ICS

suitable weight mis supported from a pulleym, which hangs in the loop ofthe cable Z and returns, by its weight, the cross-head and housing tothe normal position after the machine has been actuated. On the bottomof the cylinder R is secured a suitable hydraulic valve S for deliveryof water under pressure to the hydraulic cylinder from the supplypipe12, and it also allows water to exhaust from the cylinder through theexhaust-port n. The valve-stem 19 projects downwardly through a suitableguide in the intermediate plate 0. In the lower part of the stem iscontained a notch 19, which is engaged by a suitable slide as, which iscarried to place by a coil-spring az. On the intermediate plate 0 issupported a small lever 25 on pivot 25, the lower end of which isadapted to engage the inner end of the slide as. The upper end bears asuitable adjustable set-screw t, which projects inwardly toward theinside of the cylinder R and at such a point as to be engaged by thepiston-head at the outer end of its stroke. A suitable lever r ispivoted to the under side of the intermediate plate 0 and engages at itsouter end in a mortise in the stem 23 to the slide-valve. At its innerend it bears a weight 0" and is connected by a link 3 to a foot-lever s,by which it may be actuated. By stepping on the foot-lever s the link 3will be raised, which will raise the inner end of the lever r, carryingthe outer end down, which will depress the valve-stem p and allow it tobe engaged by the slide a; in the notch 19. This will operate the valveand the machine.

It will be noted when the piston R moves forward to actuate the housingwhich carries the spinning-roll that at the inner end of its stroke itwill come in contact with the setscrew 25, which will actuate the levert, which actuates the slide 00, and release the valve-stem p and allowthe weight 0 to carry up the valve and allow the water to exhaust fromthe cylinder. Then the weights m will carry the entire apparatus back tothe normal position. \Vhen the operative desires to again actuate themachine, he merely steps on the lever s, more water is admitted to thehydraulic cylinder, and the same process is again repeated.

If the car-wheels are very hot and roll very easily, which may causeirregularities in the rim of the same, or if for any other reasonirregularities occur in the rim which it is desired to roll or spinfurther, the operative continues to hold his foot upon the trip-lever s,which will not permit the water to exhaust from the hydraulic cylinder,and the wheel can be spun as long as desired or until the foot of theoperative releases the trip and allows the machine to return. This makesthe machine automatic or under the control of the operative, as desired.

A suitable guiding-bracket l is secured to the upper rear end of theplate 0, and to the front of the same are formed suitable guides. Avertical shaft Gr is secured to the upper end of the shaft G. Supportedon said shaft and guideway is a suitable frame or housing I, which isadapted to reciprocate up and down the shaft G and guide on thebracket 1. To the forward lower corner of the housing I is secured alever J, which operates on a pivot or fulcrum c. Projecting downwardlyand outwardly on the lower end of lever J is a spinning-roll J, which isrounded at the lower side and has a shoulder-like formation at the top.Extending from the upper end of the lever J back to the upper part ofthe bracket I are links K, which are pivoted at Z) to the bracket I andat Ct to the upper end of lever J. The connection at b has an eccentricadjustment like the eccentric adjustment of the shaft 7c, (seen in Figs.4, 10, and 11,) the adjustment being eifected by the setscrew f. Securedto the housing 1 is a cable it, which passes over suitable pulleys o oat-the top and is weighted to counterbalance the housing and carry thesame upwardly to keep tension upon the same. This cable is secured atits lower end to the housing by the pin a. To each. side of the housingare cables e, which extend downwardly, and these are secured to boltscontrolled by nuts f, which have a connection to the housing foradjusting the tension upon the cables. Between the upper plate 0 andintermediate plate 0 are supported pulleys or sheaves g, around whichthese cables pass. Secured to the ends of the shaft 11, which passesthrough the cross-head of the engine, are straight thrustbars 0, whichpass through suitable guideways to each side under the pulleys g. To therear end of these thrust-bars O are secured the lower ends of the cables6.

The portion of this improved spinning-machine bearing wheel J isdesigned for use in spinning-wheels irregularly formed, as indicated bydotted lines in Fig. 2, and the operation of the machine is such thatwhen the rolls are returned to their normal position the roll J will belifted by the weight Q) lifting the housing I.

lVhen the car-wheel is placed in position to be spun and the machine isput in operation, as the housing F is carried forward to carry the malespinning-roll H up to the female spinning-roll L, it will, by forcingthe thrust-bars 0, put stress upon the cables 6, which carry down thehousings I,.and in so doing, by the action of the links 75 on the leverJ, move the spinning-wheel J to place and roll or spin theinwardly-projecting portion, as indicated.

After a wheel is properly spun and the machine is returned to the normalposition, as

will be readily seen, the weight n will raise the upper housing 1,moving the spinningroll J out of the way, so that the car-wheel can beeasily removed and another inserted.

The-motion here secured is that required to properly adjust and bringdown the spinningroll J to secure the best formation of the metal inthis position. The central part of the wheel, while it is being spun, issupported on a little idle-roll N, which is a beveled wheel supported ona little bracket N at the top of the housing or frame F.

Having thus described my improved spinning-machine and its variousparts, I desire to state that the same can be considerably varied in itsdetails without departing from my invention. For spinning the flanges011 ordinary car-wheels the upper portion carried by the housings I,along with the shaft G and bracket I, can be entirely removed. In thisinstance the male spinning-roll II should be full and extend upwardly tocorrespond with the formation of the female roll L,as indicated bydotted lines in Fig. 6. The roll Jand its connections can be used inconnection with rolls L and II, if they are actuated by other means thanthose indicated, and answer its purpose very well. The little idle-rollN, while it serves a very useful purpose, might be dispensed with.

Other means of guiding the wheel to place could be substituted and usedfor the idlerolls T T, but these will be found very effective andconvenient for the purpose. Other variations will, no doubt, readilysuggest themselves to those skilled in the art to which this inventionpertains.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-- 1.
